HDB says that they have reached out to the owner of the unit and have checked and confirmed that there are no structural safety concerns. However, they will take the necessary action if the renovation contractor is found to be errant.

HDB says in their Facebook post:

"We’ve been alerted to a video showing old newspapers within the side walls of a balcony which was completed in 1984. We have identified the unit and gotten in touch with the flat owner.

"The windows at the balcony were installed in 1999 by a renovation contractor engaged by the flat owner. During this installation, the contractor had placed newspaper stuffing into the walls. The stuffing was discovered when the flat owner decided to replace the windows recently.

"HDB has checked and confirmed that there are no structural safety concerns. The wall has since been rectified.

"HDB is investigating and will take the necessary action if the renovation contractor is found to be errant."
